rPref is a new package for Skyline computation and some slight
generalizations (database preferences).
The Skyline of a dataset selects tuples which are Pareto-optimal with
respect to given optimization goals. Only those tuples are returned,
which are not dominated by any other tuple. A tuple dominates another
tuple if it is better than another tuple in all relevant dimensions
(strictly better at least in one dimension).
rPref offers efficient Skyline computation (algorithms are in C++) and
some related stuff (e.g. maxima of other preference orders, top-k
preference selection, some tools for visualization).
